yep... check the documentation usually routers have a web interface, that can be accessed trought any web browser... like
http://192.168.1.1
First off all Wireless need a point to access (router), and its identified with a name and its called ESSID, this can be the default name of the router or any custom name you want like "My Home", you can change the ESSID accesing the interface I told you in the first paragraph.
On your wireless computer you can try to set up the connection usually on the tray, there is a small icon that looks like two monitors, right click and then click on View Avaiable Wireless Networks.... a window will appear and there will be the ESSID name click on it, and then click on the small box that says connect..... then your wireless device will get the information from the router and you are networked now.... enjoy....
If the icon I told you is not there go START ---> Settings ----> Control Panel ---> Network and interface connections, then network connections, right click wireless network connection..
Next step will be security.... but we can help you on that after you complete the steps above...
